Now Foods Pets L-Lysine for Cats is a powdered preparation for cats, containing L-Lysine hydrochloride. It supports health of the respiratory and bone systems, boosts immunity and helps prevent herpesvirosis. This product is recommended by vets, especially by dr Barbara Royal - the founder of the Royal Treatment Veterinary Center.

L-Lysine hydrochloride is a molecule that combines the amino acid lysine with hydrogen chloride. It is a highly bioavailable form of lysine, which absorbs well and starts its action very quickly.

Lysine alone is one of the twenty protein amino acids, which not only takes part in synthesis of proteins but also has a positive effect on the immune and bone systems.

It has the following properties:
Healthy bone system in cats at any age
Lysine is an exogenous amino acid for cats, so it has to be supplied with food. It allows biosynthesis of proteins present in the entire body, including those in the muscles and bones. It supports proper absorption of calcium, which is necessary for strong and durable bones. Lysine plays a particularly important role in development of kittens and helps to maintain the normal condition of the movement system in older cats.

In addition, lysine is necessary for the synthesis of collagen, which is the most common protein in the organisms of cats and other species. For example, it is a part of cartilage, tendons, bones and ligaments. Its correct amount and structure conditions health of these structures. It also has a positive effect on blood vessel walls and joints.

Better immunity and enhanced protection against diseases
Cats of all ages have some risk of getting infected with FHV-1 herpesvirus, which can cause inflammation of the upper respiratory tract (nasal cavity and trachea), cough, runny nose, fever, conjunctivitis or corneal ulceration. This virus is the most likely to attack unvaccinated cats and these which are exposed to stress (for example due to travelling), as well as kittens and older cats.

L-Lysine can act prophylactically and also support treatment during an infection. During multiplication, herpesviruses produce proteins rich in arginine, which are necessary for the replication process. Lysine can compete with arginine and build into the protein needed by the virus, which disturbs its multiplication. This can result in less severe symptoms and shorter duration of infection.

Better appearance and general condition of a cat
Lysine is the key amino acid for proper synthesis of enzymes, hormones and antibodies that also increase immunity. The right amount of enzymes and well-functioning hormonal metabolism guarantee efficient course of processes in the body. This favourably affects a cat’s coat, claws, teeth, and also improves its general condition and health.

Lysine is also involved in antioxidative processes, thanks to which it helps protect against the harmful effects of free radicals, which may be the cause of many serious diseases. In addition, this amino acid is necessary for the synthesis of L-carnitine. It is a transporter of fatty acids to the mitochondria, thanks to which it stimulates the production of energy that can be used for proper muscle work. It is also crucial for the efficient metabolism of lipids, which promotes faster regeneration and recovery of cats in cachexia or those abandoned by their caretakers.

To sum up, Now Foods Pets L-Lysine for Cats is a preparation supporting a cat’s immunity and health. It prevents infections and has a beneficial effect on the feline organism of any age.

Lysine belongs to the group of 9 essential amino acids delivered into the body from outside (with food or as a supplement) .It is a building substance of protein (the muscle protein). It is available in food of animal origin (meat, dairy products) and vegetable (legumes). It plays an important role in many physiological processes (absorption of calcium, production of enzymes, hormones and antibodies), and arginine is a component of supplements that increase the synthesis of growth hormone (HGH stimulators). In the form of hydroxylysine (a component of collagen) recommended for the treatment of sports injuries, and prevention. In the case of stress and excessive physical and psychological overloads, it is recommended due to the function of lowering cortisol levels. Also it applies in medicine, in the treatment of anxiety and herpes. The share of lysine intake of daily doses of amino acids should not exceed 5.1%. Available for purchase at
In the processes of digestion of protein matter, as a result of decarboxylation of lysine, may be converted into cadaverine (biogenic amine) having a strong toxicity.
Dosage: the lack of a well-defined standard daily intake of lysine. The supplementation dosages regularly used: with arginine 500 mg - 2g (before bedtime) pre- and post-workout optionally with other amino acids.
